          Description

          Base oil: CL100、CL101、CL102、CL103、CL104、CL105
          Vacuum pump oil: CL1506、CL1514、CL1525

          Perfluoropolyether oil is a colorless, transparent liquid at room temperature. It is resistant to high temperatures, chemical corrosion, oxidation, and radiation. It is primarily used as a lubricant and vacuum pump oil. Due to its extremely high stability, safety, and particularly its remarkable reliability under harsh conditions, no other working medium can match perfluoropolyether oil in such demanding environments.

          Applications

          • Nuclear Industry: When used as a bearing lubricant in ultracentrifuges, PFPE is the only lubricant capable of resisting chemical impacts from uranium hexafluoride (UF6) above 130°C and maintaining low vapor pressure.
          • Chemical Industry: In environments with chemically corrosive gases, PFPE can be used as a lubricant for various vacuum pumps, compressors, and valves.
          • Medicine and Food: PFPE is safe and non-toxic, suitable for lubricating seals and protecting mechanical equipment, thereby extending its service life.
          • Electrical Industry: It serves as a lubricant for arc-resistant switches and sliding contact components.
          • Mechanical Engineering: PFPE can be used for high-speed bearings, especially in extremely high temperatures and harsh environments, extending bearing life by 5 to 50 times.
          • Automobile Industry: Suitable for use in starters, electric mirrors, door locks, manual (or electric) window lifts, handbrake cables, main reducers, disc brake caliper pistons, clutch release bearings, and brake master cylinders. It helps reduce component friction, lower noise, and enhance user comfort.
          • Electronics Industry: Suitable as mechanical vacuum pump oil for plasma etching of integrated circuits.
          • Magnetic Media Industry: Can be used as a lubricant for hard drives, disks, and other magnetic recording media on instruments such as computers, DVD players, and automatic recording devices.
          • Aerospace and Military: Suitable for lubrication and sealing of gear pumps, valves, regulators, pressure gauges, metal fittings, and threaded fasteners in liquid fuel rocket engines' fuel and oxidizer systems. It is also used in spacecraft oxygen supply systems for pipelines, valves, seals, and bearings of axial flow fans that deliver breathing oxygen, as well as for lubrication and sealing of astronaut oxygen supply device components.
